43 FLAT CABLE CORE ASSEMBLY
Explanation of Part Numbers:
– Digits 1 & 2 = Product Class
– Digits 3 & 4 = Material Grade
Flat Cable Snap-Its for use on multi-conductor flat cables to suppress common-mode conducted EMI from 1MHz to hundreds of MHz. These Flat Cable Snap-Its are available in two ferrite materials, 31 and 43. The polypropylene cases are meeting the RoHS restrictions of hazardous substances and have a flammability rating of UL 94 V-0.
The Expanded Cable and Suppressor Kit (Part number 0199000005) contains several Flat Cable Snap-It assemblies.

Flat Cable Snap-It assemblies are controlled for impedances only. Minimum impedance values are specified for the + marked frequencies. The minimum impedance is typically the listed impedance less 20%.
Centered, single turn impedance tests on the 31 and 43 material parts are performed on the E4991A/HP4291B Impedance Analyzer. Cores are tested with the shortest practical wire length.
| Typical Impendance (Ω) | |
| 10 MHz | 60 |
| 25 MHz+ | 110 |
| 100 MHz+ | 290 |
| 250 MHz | 435 |
